In practice, it may be quite difficult to distinguish stored charge effects (in insulators) from piezoelectric effects.

在实际工作中，区分储存电荷效应(在绝缘体中)和压电效应可能是相当困难的。

This paper obtains a more accurate expression by analyzing charge-control equation and calculates expression of stored charge.

本文通过分析电荷控制方程得到了更精确的表达式，并用这种方法计算了储存电荷法的公式。

Piezoelectric or stored charge effects: the creation of charge unbalances (and thus current flow or voltage shift) due to mechanical stress.

压电或储存电荷效应：由于机械应力产生的电荷不平衡(从而产生了电流或电压偏置)。

For the first 35 miles, the Volt can drive gas- and tailpipe-emissions-free using a full charge of electricity stored in its 16-kWh lithium-ion battery.

Although the exact mechanism is still not entirely understood, it turns out that illuminating the liquid crystal, applying a voltage across a small region of it, and then turning off the light source causes a small amount of charge to be stored in that region.

ECONOMIST: Just press print

The amount of charge that can be stored depends on the surface area of the electrodes, the strength and composition of the insulation between them, and how close they are together.
